Maximum temperature in a fan depends of its configuration : - a direct coupling standard fan can be used with a temperature of air from +40°C up to +90°C, depending model. - with a belt-driven (with cooling fan), the temperature can raise up to +150°C (+350°C), depending model. Some specific fans (like fans for industrial ovens or oven circulators) are designed for air up to +300°C continuous. Our range of smoke extract fans are designed and certified according EN 12101-3 (F300/120 or F400). With our range of 'heavy-duty' fans, we can reach temperature up to +900°C (depending model and configuration). To find these fans, you can refine your selection using the 'thermometer' button in the attributes (below left).
